It presents the evaluation results, their justifications, and the conformance results. This Validation Report is not an endorsement of the Target of Evaluation by any agency of the U.S. government, and no warranty is either expressed or implied. The evaluation was performed by the Booz Allen Hamilton Inc. Common Criteria Testing Laboratory (CCTL) in Linthicum Heights, Maryland, United States of America, and was completed in January 2016. The information in this report is largely derived from the Evaluation Technical Report (ETR) and associated test reports, all written by Booz Allen. The evaluation determined that the product is both Common Criteria Part 2 Extended and Part 3 Conformant, and meets the assurance requirements set forth in the Network Device Protection Profile (NDPP). The Target of Evaluation (TOE) is the Gigamon GigaVUE HD8, HD4, HC2, HB1, TA10, and TA40 with software version 4.4.03 standalone network device. This device is used to receive out- of-band copied network data from external sources and forward that data to one or many tool ports for packet capture and/or analysis based on selected criterial. However, the evaluated TOE functionality includes only the security functional behavior that is defined in the claimed NDPP. The TOE identified in this Validation Report has been evaluated at a NIAP approved Common Criteria Testing Laboratory using the Common Methodology for IT Security Evaluation (Version 3.1, Rev 4) for conformance to the Common Criteria for IT Security Evaluation (Version 3.1, Rev 4), as interpreted by the Assurance Activities contained in the NDPP. This Validation Report applies only to the specific version of the TOE as evaluated. The evaluation has been conducted in accordance with the provisions of the NIAP Common Criteria Evaluation and Validation Scheme and the conclusions of the testing laboratory in the evaluation technical report is consistent with the evidence provided. The validation team provided guidance on technical issues and evaluation processes, and reviewed the individual work units of the ETR for the NDPP Assurance Activities. The validation team found that the evaluation showed that the product satisfies all of the functional requirements and assurance requirements stated in the Security Target (ST). Therefore the validation team concludes that the testing laboratory’s findings are accurate, the conclusions justified, and the conformance results are correct. The conclusions of the testing laboratory in the evaluation technical report are consistent with the evidence produced. The technical information included in this report was obtained from the Gigamon GigaVUE Security Target, Version 1.0, dated December 11, 2015 and analysis performed by the Validation Team. VALIDATION REPORT Gigamon GigaVUE 5 2 Identification The CCEVS is a joint National Security Agency (NSA) and National Institute of Standards and Technology (NIST) effort to establish commercial facilities to perform trusted product evaluations. Under this program, security evaluations are conducted by commercial testing laboratories called Common Criteria Testing Laboratories (CCTLs). CCTLs evaluate products against Protection Profiles containing Assurance Activities, which are interpretations of CEM work units specific to the technology described by the PP. The NIAP Validation Body assigns Validators to monitor the CCTLs to ensure quality and consistency across evaluations. Developers of information technology products desiring a security evaluation contract with a CCTL and pay a fee for their product’s evaluation. Upon successful completion of the evaluation, the product is added to NIAP’s Product Compliance List. Table 1 provides information needed to completely identify the product, including:  The Target of Evaluation (TOE): the fully qualified identifier of the product as evaluated.  The Security Target (ST), describing the security features, claims, and assurances of the product.  The conformance result of the evaluation.  The Protection Profile to which the product is conformant.  The organizations and individuals participating in the evaluation.

The assumed level of expertise of the attacker for all the threats identified below is Enhanced-Basic.  T.ADMIN_ERROR — An administrator may unintentionally install or configure the TOE incorrectly, resulting in ineffective security mechanisms.  T.TSF_FAILURE — Security mechanisms of the TOE may fail, leading to a compromise of the TSF.  T.UNDETECTED_ACTIONS — Malicious remote users or external IT entities may take actions that adversely affect the security of the TOE. These actions may remain undetected and thus their effects cannot be effectively mitigated.  T.UNAUTHORIZED_ACCESS — A user may gain unauthorized access to the TOE data and TOE executable code. A malicious user, process, or external IT entity may masquerade as an authorized entity in order to gain unauthorized access to data or TOE resources. A malicious user, process, or external IT entity may misrepresent itself as the TOE to obtain identification and authentication data.  T.UNAUTHORIZED_UPDATE — A malicious party attempts to supply the end user with an update to the product that may compromise the security features of the TOE.  T.USER_DATA_REUSE — User data may be inadvertently sent to a destination not intended by the original sender. 3.3 Objectives The following identifies the security objectives of the TOE. These security objectives reflect the stated intent to counter identified threats and/or comply with any security policies identified.  O.PROTECTED_COMMUNICATIONS — The TOE will provide protected communication channels for administrators, other parts of a distributed TOE, and authorized IT entities.  O.VERIFIABLE_UPDATES — The TOE will provide the capability to help ensure that any updates to the TOE can be verified by the administrator to be unaltered and (optionally) from a trusted source.  O.SYSTEM_MONITORING — The TOE will provide the capability to generate audit data and send those data to an external IT entity.  O.DISPLAY_BANNER — The TOE will display an advisory warning regarding use of the TOE. VALIDATION REPORT Gigamon GigaVUE 7  O.TOE_ADMINISTRATION — The TOE will provide mechanisms to ensure that only administrators are able to log in and configure the TOE, and provide protections for logged-in administrators.  O.RESIDUAL_INFORMATION_CLEARING — The TOE will ensure that any data contained in a protected resource is not available when the resource is reallocated.  O.SESSION_LOCK — The TOE shall provide mechanisms that mitigate the risk of unattended sessions being hijacked.  O.TSF_SELF_TEST — The TOE will provide the capability to test some subset of its security functionality to ensure it is operating properly. 3.4 Clarification of Scope All evaluations (and all products) have limitations, as well as potential misconceptions that need clarifying. This text covers some of the more important limitations and clarifications of this evaluation. Note that:  As with any evaluation, this evaluation only shows that the evaluated configuration meets the security claims made, with a certain level of assurance. The level of assurance for this evaluation is defined within the Security Requirements for Network Devices, Version 1.1, 08 June 2012 (including the optional HTTPS, TLS, and SSH requirements) with Errata #3 to which this evaluation claimed exact conformance.  Consistent with the expectations of the Protection Profile, this evaluation did not specifically search for, nor seriously attempt to counter, vulnerabilities that were not “obvious” or vulnerabilities to objectives not claimed in the ST. The CEM defines an “obvious” vulnerability as one that is easily exploited with a minimum of understanding of the TOE, technical sophistication and resources.  The functionality evaluated is scoped exclusively to the security functional requirements specified in the Section 6 of the Security Target. The traffic forwarding functionality included in the product and described in Section 1.3 of the Security Target was not assessed as part of this evaluation. All other functionality provided by the devices needs to be assessed separately and no further conclusions can be drawn about their effectiveness. The evaluated configuration of the TOE includes the Gigamon GigaVUE product that is comprised of one or more of the product models listed in Table 2 and includes version 4.4.03 of its software. There are no separately purchased licenses or components that must be acquired in order to operate the product in its evaluated configuration. The TOE includes all the code that enforces the policies identified (see Section 5). The SCP, SFTP, FTP, and TFTP interfaces to the update server in order to download product updates and Telnet for remote administration are excluded from the evaluated configuration. Additionally, the TOE must be configured into its enhanced security mode in order to enforce the cryptographic algorithms and ciphersuites that are claimed in the Security Target. The exclusion of these functionalities do not affect compliance to the U.S. Government Protection Profile for Security Requirements for Network Devices Version 1.1. VALIDATION REPORT Gigamon GigaVUE 8 4 Architectural Information Note: The following architectural description is based on the description presented in the Security Target. 4.1 TOE Introduction GigaVUE HD8, HD4, HC2, HB1, TA10 and TA40 with software version 4.4.03 (herein referred to as GigaVUE or the TOE) uses the Gigamon Forwarding Policy to receive out-of- band copied network data from external sources (TAP or SPAN port) and forward that copied network data to one or many tool ports for packet capture or analyzing tools based on user selected criteria. GigaVUE can also copy the network traffic itself when sitting in-line with the network flow using passive, inline and bypass taps or any combination. GigaVUE features extensive filtering abilities enabling authorized users to forward precise customized data flows of copied data from many sources to a single tool, from a single source to many tools, or from many sources to many tools. The TOE consists of one or more models as specified below. Each of the models includes software version 4.4.03. 4.2 Physical Boundaries The TOE is comprised of both software and hardware. The hardware is comprised of the following: Table 2 – Hardware Models and Specifications (HD8 and HD4 Series) Property HD8 HD8 HD4 HD4 Model Number GVS-HD8A1 GigaVUE-HD8 base unit w/ chassis, CLI GVS-HD8A2 GigaVUE-HD8 base unit w/ chassis, CLI GVS-HD4A1 GigaVUE-HD4 base unit w/ chassis, CLI GVS-HD4A2 GigaVUE-HD4 base unit w/ chassis, CLI Size 14RU 14RU 5RU 5RU Total Slots 8 8 5 5 Power AC DC AC DC Control Cards 1 or 2 1 or 2 1 1 Port Blades PRT-H00-X12G04 Port Blade, HD Series, 12x10G 4x1G PRT-H00-X12TS Port Blade, HD Series, 12x10G Time Stamp PRT-H00-X04G44 Port Blade, HD Series, 4x10G 44x1G PRT-H00-Q02X32 Port Blade, HD Series, 2x40G 32x10G (24 10G + 2 40G or 32 10G active) PRT-HD0-Q08 Port Blade, HD Series, 8x40G PRT-HD0-C01 Port Blade, HD Series, 1x100G PRT-HD0-C02X08 Port Blade, HD Series, 2x100G CFP cages + 8x10G cages PRT-HD0-C02X08A Port Blade, HD Series, 2x100G CFP2 cages + 8x10G cages GigaSMART Module: SMT-HD0-GigaSMART, HD Series blade (includes Slicing, Masking, Source Port,& GigavuE Tunneling De-Encapsulation SW Power Supplies 4 4 2 2 Processor PowerPC 600 PowerPC 600 PowerPC 600 PowerPC 600 Memory (RAM) CCv1: 2GB CCv2: 4GB CCv1: 2GB CCv2: 4GB CCv1: 2GB CCv2: 4GB CCv1: 2GB CCv2: 4GB Logical Drive Capacity CCv1: 2GB CCv2: 8GB CCv1: 2GB CCv2: 8GB CCv1: 2GB CCv2: 8GB CCv1: 2GB CCv2: 8GB VALIDATION REPORT Gigamon GigaVUE 9 Fixed Ports None None None None Configurable Ports Provided by Port Blades Provided by Port Blades Provided by Port Blades Provided by Port Blades Table 3 – Hardware Models and Specifications (HC2 Series) Property HC2 HC2 Model Number GVS-HC201 GigaVUE-HC2 base unit w/ chassis, CLI, GVS-HC202 GigaVUE-HC2 base unit w/ chassis, CLI Size 2RU 2RU Front Bays 4 4 Rear Bays 1 1 Power AC DC Main Board 1 1 TAP Modules TAP-HC0-D25AC0 TAP module, HC Series, SX/SR Internal TAP Module 50/125, 12 TAPs TAP-HC0-D25BC0 TAP module, HC Series, SX/SR Internal TAP Module 62.5/125, 12 TAPs TAP-HC0-D35CC0 TAP module, HC Series, LX/LR Internal TAP Module, 12 TAPs TAP-HC0-G100C0 TAP and Bypass module, HC Series, Copper, 12 TAPs or BPS pairs Bypass Combo Modules BPS-HC0-D25A4G Bypass Combo Module, HC Series, 4 SX/SR 50/125 BPS pairs, 16 10G cages BPS-HC0-D25B4G Bypass Combo Module, HC Series, 4 SX/SR 62.5/125 BPS pairs, 16 10G cages BPS-HC0-D35C4G Bypass Combo Module, HC Series, 4 LX/LR BPS pairs, 16 10G cages Port Modules PRT-HC0-X24 Port Module, HC Series, 24x10G PRT-HC0-Q06 Port Module, HC Series, 6x40G GigaSMART Modules: SMT-HC0-R GigaSMART, HC Series rear module (includes Slicing, Masking, Source Port & GigaVUE Tunneling De-Encapsulation SW) SMT-HC0-X16 GigaSMART, HC Series, Front Module, 16 10G cages (includes Slicing, Masking, Source Port & GigaVUE Tunneling De-Encapsulation SW Power Supplies 2 2 Processor PowerPC 600 PowerPC 600 Memory (RAM) 4GB 4GB Logical Drive Capacity 8GB 8GB Fixed Ports PTP IEEE 1588 Stack Mgmt Port Mgmt Console PTP IEEE 1588 Stack Mgmt Port Mgmt Console Configurable Ports Provided by TAP Modules, Bypass combo modules, Port Modules Provided by TAP Modules, Bypass combo modules, Port Modules Table 4 – Hardware Models and Specifications (HB1 Series) Property HB1 HB1 Model Number GVS-HB101-0416 branch node GVS-HB102-0416 branch node Size 1RU 1RU Cages 4 10G cages 8 1G cages 4 10G cages 8 1G cages VALIDATION REPORT Gigamon GigaVUE 10 Copper 8 1G 8 1G Power AC DC Power Supplies 1 1 Processor PowerPC 600 PowerPC 600 Memory (RAM) 2GB 2GB Logical Drive Capacity 2GB 2GB Fixed Ports PTP 1588 Mgmt Console 8 10/100/1000 Ports, 8 1G Ports (SFP), 4 1G/10G (SFP+) PTP 1588 Mgmt Console 8 10/100/1000 Ports, 8 1G Ports (SFP), 4 1G/10G (SFP+) Configurable Ports None None Table 5 – Hardware Models and Specifications (TA10 Series) Property TA10 TA10 Model Number GigaVUE-TA10 Edge Traffic Aggregation Node (SKU GVS-TAX01) GigaVUE-TA10 Edge Traffic Aggregation Node (SKU GVS-TAX01) Size 1RU 1RU Power AC DC Power Supplies 2 2 Processor PowerPC e500 PowerPC e500 Memory (RAM) 4GB 4GB Logical Drive Capacity 8GB 8GB Fixed Ports Mgmt Console 48 1G/10G Ports (SFP+) 4 10G/40G QSFP Ports Mgmt Console 48 1G/10G Ports (SFP+) 4 10G/40G QSFP Ports Configurable Ports None None Table 6 – Hardware Models and Specifications (TA40 Series) Property TA40 TA40 Model Number GigaVUE-TA40 Edge Traffic Aggregation Node (SKU GVS-TAQ01) GigaVUE-TA40 Edge Traffic Aggregation Node (SKU GVS-TAQ01) Size 1RU 1RU Power AC DC Power Supplies 2 2 Processor PowerPC e500 PowerPC e500 Memory (RAM) 4GB 4GB Logical Drive Capacity 8GB 8GB Fixed Ports Mgmt Console 32 10G/40G QSFP Ports Mgmt Console 32 10G/40G QSFP Ports Configurable Ports None None VALIDATION REPORT Gigamon GigaVUE 11 The TOE resides on a network and supports (in some cases optionally) the following hardware, software, and firmware in its environment: Table 7 – Operational Environment Components Component Usage/Purpose Description for TOE performance Management Workstation Any general-purpose computer that is used by an administrator to manage the TOE. The TOE can be managed remotely, in which case the management workstation requires an SSH client to access the CLI or a web browser to access the web GUI, or locally, in which case the management workstation must be physically connected to the TOE using the serial port and must use a terminal emulator that is compatible with serial communications. Update Server A general-purpose computer that includes a web server and is used to store software update packages that can be retrieved by the TOE using TLS/HTTPS. The update server can be a server maintained by Gigamon or it can be set up locally in the Operational Environment by an administrator if the TOE’s deployment prevents it from being able to access Gigamon’s web domain. LDAP Server A system that is capable of receiving authentication requests using LDAP over TLS and validating these requests against identity and credential data that is defined in an LDAP directory. NTP Server A server that provides reliable time data to the TOE’s system clock so that the timestamps on its audit records can be synchronized with other devices in the Operational Environment that connect to the same server. Syslog Server An SFTP server that can be used by the TOE to transfer its stored syslog audit data to using SSH. VALIDATION REPORT Gigamon GigaVUE 12 5 Security Policy 5.1 Security Audit The TOE contains mechanisms to generate audit data to record predefined events on the TOE. Each audit record includes timestamp, event type, and subject identity where applicable. The audit records are stored locally and sent securely to the environmental syslog server using SSH. The TOE’s local audit data storage is used to continue recording audit data in the event that communications between the TOE and the syslog server fail. Only authorized administrators can delete locally stored audit data. 5.2 Cryptographic Support The TOE uses sufficient security measures to protect its data in transmission by implementing cryptographic methods and trusted channels. The TOE uses SSH to secure the remote CLI and Syslog Server trusted channels. The TOE also uses TLS/HTTPS to secure the trusted channels for the secure WebGUI, update server and LDAP server. SSH and TLS/HTTPS protocols implement Diffie-Hellman and RSA based key generation and key establishment methods. The cryptographic algorithms are provided by a FIPS validated cryptographic module (CMVP certificate #2128). Cryptographic keys are generated using the CTR_DRBG provided by this module. The TOE zeroizes all plaintext secret and private keys by overwriting the memory location occupied by the keys and deallocating their memory locations. In the evaluated configuration the TOE operates in “Enhanced Security Mode” which is used to restrict algorithms to meet the PP requirements. The following table contains the CAVP algorithm certificates. Table 4 CAVP References Algorithm Cert. # AES-CBC-128, AES-CBC-256 2273 RSA 1166 CTR_DRBG (AES) 281 SHA-1, SHA-256, SHA-512 1954 HMAC-SHA-1, HMAC-SHA-256, HMAC-SHA-512 1391 5.3 User Data Protection The TOE ensures that packets transmitted from the TOE do not contain residual information from previous packets. The TOE ensures this by zeroizing the data upon allocation of memory. Residual data is never transmitted from the TOE. 5.4 Identification and Authentication Users authenticate to the TOE as administrators via the local console, remote CLI, or remote web GUI. Administrators are authenticated through a username and password defined on the TOE, a username and password defined on an environmental LDAP server, or username and SSH public key. The TOE does not allow any TSF functionality to be performed prior to successful authentication other than a display of the warning banner. When authenticating via the local console, any input credential data is not echoed back to the screen by the TSF. VALIDATION REPORT Gigamon GigaVUE 13 5.5 Security Management The TOE maintains the roles of Admin, Monitor, and Operator. Of these roles, only the Admin role is authorized to manage the behavior of the TSF. The other roles are used to perform actions that are entirely outside the scope of the claimed Protection Profile. All administration of the TOE can be performed locally using a management workstation connected to the serial console, remotely using a CLI from a management workstation that communicates with the TOE using SSH, or remotely using a web GUI from a management workstation that communicates with the TOE using TLS/HTTPS. 5.6 Protection of the TSF The TOE is expected to ensure the security and integrity of all data that is stored locally and accessed remotely. The TOE stores password data as SHA-512 hashes and does not provide a mechanism to access any pre-shared keys, symmetric keys, or private keys. The TOE maintains system time with either its local hardware clock or with NTP server synchronization. At start-up, the TOE performs an integrity test of its cryptographic module, known answer tests for cryptographic services, self-tests of all components connected to the motherboard (memory, CPU, Ethernet controllers, etc.), and any components that are connected to the device via PCIe interfaces. Software updates are securely downloaded from a remote server using TLS/HTTPS and are verified using a digital signature prior to being applied. 5.7 TOE Access The TOE can terminate inactive sessions after an administrator-configurable time period. The TOE also allows users to terminate their own interactive session. Once a session has been terminated, the TOE requires the user to re-authenticate to establish a new session. The TOE also displays a configurable warning banner prior to use of the TSF. 5.8 Trusted Path/Channels The TOE establishes trusted channels to the Operational Environment using TLS for LDAP server communications, SSH for syslog server communications, and TLS/HTTPS for update server communications. Administrators can establish trusted paths to the TOE using SSH for remote CLI administration and TLS/HTTPS for remote web GUI administration. All cryptographic functionality supporting the use of these trusted channels and paths is facilitated by the FIPS-validated cryptographic module contained within the TOE. In the evaluated configuration, the TOE will be configured into its enhanced security mode, which limits the cryptographic algorithms and cipher suites used for trusted communications to those that are specified in the Security Target.

To use the product in the evaluated configuration, the product must be configured as specified in the Gigamon GigaVUE Supplemental Administrative Guidance, Version 1.0 (AGD) document. VALIDATION REPORT Gigamon GigaVUE 16 8 IT Product Testing This section describes the testing efforts of the developer and the evaluation team. It is derived from information contained in the proprietary Evaluation Technical Report for a Target of Evaluation “Gigamon GigaVUE” Evaluation Technical Report v1.0 dated January 29, 2016, as summarized in the publicly available Assurance Activity Report for a Target of Evaluation “Gigamon GigaVUE” Assurance Activities Report v1.0 dated January 29, 2016 . 8.1 Test Configuration The evaluation team configured each tested model of the TOE according the Gigamon GigaVUE Supplemental Administrative Guidance, Version 1.0 (AGD) document for testing. The evaluation team set up a test environment for the independent functional testing that allowed them to perform all test assurance activities across the GigaVUE HD4 and TA-40 models over the SFR relevant interfaces. A sampling of test assurance activities were also tested multiple times on the GigaVUE HB1, HC2, and TA-10 models over all SFR relevant interfaces. The testing performed has a complete overlap between the tested models and interfaces to validate that the TOE performs the same regardless of the specific model. The selection of models for testing was based upon ensuring that all of the SFR relevant interfaces and all TOE software images were tested and that they produced the same results when tested. The AC power supplied GigaVUE HD4, HC2, HB1, TA-10, and TA-40 models running Gigamon GigaVUE-OS were deployed in the test laboratory as a representative set of the TOE’s models. These models were used for the execution of the independent functional testing and vulnerability testing. The evaluation team performed testing of the TSF functionality across all of the sampled models as well as each of the three available management interfaces (local console, remote CLI, remote GUI). The full set of tests were replicated for each model and the tests were developed to stimulate each applicable TSF relevant interface; which would fully test all combinations of the selected models and their TSF relevant interfaces. The testing performed on each physical interface of each sampled model, with the same logical interface SFR functionality, validated that the internal processing of the TOE would produce the same results regardless of the specific model or physical interface used to initiate or perform the processing. The testing is consistent with the use of the interfaces defined within the ST. Thus, the testing of the interfaces was based upon testing SFR functionality related to user actions over each interface. The TOE was configured to communicate with the following environment components:  Management Workstation for local and remote administration  NTP Server to acquire the time  Local Update Server to perform TOE software updates  LDAP Server to perform external authentication  Syslog Server to transfer audit records remotely from the TOE The following test tools were installed on a separate workstation (management workstation)  WireShark: version 1.12.6  Bitvise SSH Client: version 6.43 *Only the test tools utilized for functional testing have been listed. VALIDATION REPORT Gigamon GigaVUE 17 8.2 Developer Testing No evidence of developer testing is required in the Assurance Activities for this product. 8.3 Evaluation Team Independent Testing The test team's test approach was to test the security mechanisms of the Ciena CES models by exercising the external interfaces to the TOE and viewing the TOE behavior on the platform. The ST and the independent test plan were used to demonstrate test coverage of all SFR testing assurance activities as defined by the NDPP for all security relevant TOE external interfaces. TOE external interfaces that will be determined to be security relevant are interfaces that  change the security state of the product,  permit an object access or information flow that is regulated by the security policy,  are restricted to subjects with privilege or behave differently when executed by subjects with privilege, or  invoke or configure a security mechanism. Security functional requirements were determined to be appropriate to a particular interface if the behavior of the TOE that supported the requirement could be invoked or observed through that interface. The evaluation team tested each interface for all relevant behavior of the TOE that applied to that interface. 8.4 Evaluation Team Vulnerability Testing The evaluation team created a set of vulnerability tests to attempt to subvert the security of the TOE. These tests were created based upon the evaluation team's review of the vulnerability analysis evidence and independent research. The evaluation team conducted searches for public vulnerabilities related to the TOE. A few notable resources consulted include securityfocus.com, the cve.mitre.org, and the nvd.nist.gov. Near the completion of the evaluation, the evaluators revisited their search for known vulnerabilities and identified a memory leak vulnerability and the vendor updated the TOE to incorporate a patch to address the vulnerability. Upon the completion of the vulnerability analysis research and initially discovering no known vulnerabilities, the team identified several generic vulnerabilities upon which to build a test suite. These tests were created specifically with the intent of exploiting these vulnerabilities within the TOE or its configuration. The team tested the following areas:  Eavesdropping on Communications The TOE’s implementation of trusted communications protocols should be correct and should not use weak ciphers or expose sensitive data in a way that would allow an attacker to break the security of the channel and gain access to TSF data in transit.  Port Scanning Remote access to the TOE should be limited to the standard TOE interfaces and procedures. This test enumerates network port and service information to determine if any ports were open and running services outside of the TOE standard configuration.  Web Interface Vulnerability Identification The WebGUI that is used to manage the TOE should not contain implementation flaws such as cross-site scripting or SQL database injection vulnerabilities that would allow a user to gain or escalate their privileges on the system or to inject data into the TOE that may interfere with its functionality and cause it to enter an unknown state.  SSH Timing Attack VALIDATION REPORT Gigamon GigaVUE 18 The CLI interface to the TOE should not behave differently whether a valid or invalid username is supplied to it so that an attacker with no knowledge of the user database cannot enumerate valid user accounts on the TOE.  CLI Privilege Escalation The TOE software is built on the Linux kernel, so an attacker should not be able to successfully ‘break out’ of the management CLI into a general-purpose Linux shell such as bash or ksh.  Force SSHv1 This attack determines if the client will accept both SSHv1 and SSHv2 connections when the TOE claims to only support SSHv2. The TOE successfully prevented any attempts of subverting its security. VALIDATION REPORT Gigamon GigaVUE 19 9 Results of the Evaluation The results of the assurance requirements are generally described in this section and are presented in detail in the proprietary ETR. The reader of this document can assume that all Assurance Activities and work units received a passing verdict. A verdict for an assurance component is determined by the resulting verdicts assigned to the corresponding evaluator action elements. The evaluation was conducted based upon CC version 3.1 rev 4 and CEM version 3.1 rev 4. The evaluation determined the Ciena CES TOE to be Part 2 extended, and meets the SARs contained the PP. Additionally the evaluator performed the Assurance Activities specified in the NDPP. The following evaluation results are extracted from the non-proprietary Evaluation Technical Report provided by the CCTL, and are augmented with the validator’s observations thereof. 9.1 Evaluation of the Security Target (ASE) The evaluation team applied each ASE CEM work unit.

Embodies the “Super” role. Authorized Administrator The claimed Protection Profile defines an Authorized Administrator role that is authorized to manage the TOE and its data. For the TOE, this is considered to be any user with the ‘admin’ role. Connection One to One simple flows between a network port and a tool port. Copied Network Data The copied network traffic that is filtered and forwarded by the TOE to a physically connected analysis tool. Filter Rules used to create customized data streams which include or exclude data between connections. ‘Pre’ filters operate at the Network Port (ingress to TOE) ‘Post’ filters operate at the Tool Port (egress from the TOE). GigaStream A grouping of multiple ports (based on IEEE 802.1 specification) into a logical bundle to increase bandwidth. GigaVUE The TOE; it provides secure out-of-band data access for enterprise networks. Flow Map Provide greater capabilities than connections by allowing the distribution of network traffic based on a set of user-defined rules, with each rule directing the traffic to one or more tool ports. Module Swappable hardware devices that are inserted into the expansion slots of the TOE. Modules can change the functionality of the TOE to include an internal TAP, bypass TAP, Gigabit Ethernet ports, and stacking ports. Network Port Where data arrives into the TOE. The ports which receive copied network data for the TOE. SPAN or TAPs are connected to a network port to provide data into the TOE. Production Network The network(s) which the GigaVUE receives or copies network traffic from. Note: The TOE takes no action on this traffic. When the TOE is in-line with the production network traffic, the traffic received by the TOE is the same traffic that is sent back out to the production network. During internal GigaVUE processes, this traffic is copied becoming the Copied Network Data. Security Administrator Synonymous with Authorized Administrator. Stacking The ability to connect one TOE to another TOE and have data flow between them. System Administrator The class of TOE administrators that are tasked with managing the TOE’s deployment and configuration. Tool Port Where data leaves the TOE. The ports to which the TOE sends data that has been filtered and directed. Tools are connected to the tool ports and receive copied data from the TOE. Trusted Channel An encrypted connection between the TOE and a system in the Operational Environment. Trusted Path An encrypted connection between the TOE and the application an Authorized Administrator uses to manage it (web browser, terminal client, etc.). User In a CC context, any individual who has the ability to manage TOE functions or data. VALIDATION REPORT Gigamon GigaVUE 26 15 Bibliography 1.
